IMPROVEMENT iN VAPOR-BURNERS.

Speciiication forming part of Letters Patent No. 104,009, dated June 7, 1870.

To all whom it may concern:

Be it known that I, DAVrD It. FLETCHER, of Covington, Kenton County, State of Kentucky, haveinvented certain new and useful Improvements in Gas-Generating Burners for Gasoline and Light Oils; and I do hereby declare the followin g to be a sufficiently full, clear, and exact description thereof to enable one skilled in the art to which my invention appertains to make and use it, reference being had to the accompanying drawing, making part of this specification.

Nature and Objects 0j' Intention.

This invention relates to a gas-generating burner; and my improvement consists in constructing such a burner with an inwardly-daring Haine-aperture, the sides of which comein contact with a portion of the flame, and are constructed with channels, in which the oil, in iiowing through, is vaporized by the'heat of the dame, as will be more fully set forth hereinafter.

Description Q7" the Accompanying Drawing.

'Figure l is a perspective View of a lamp with my improved burner attached. Fig. 2 is a perspective View of the burner detached, with one side partly sectionized to exhibit the interior construction. Fig. 3 is a side elevation or exterior view of the burner, showing` the passages in the body of the burner in dotted lines, the arrows representing the direction of the current of fluid and gas.

General Description.

A is the body of the burner, attached to the pipe B in the manner shown, a cock, C, intervening between the burner and fluid-reservoir D. The gas, as it is generated, in the manner hereinafter described, escapes at the aperture a, and the sides a! a of the flameaperture, which spread and form the jet,'iiare inward, as shown, so as to project over the aperture a, for the purpose of enabling the body of the burner to absorb and conduct to the iiuid passing through it a sufficient amount of heat to convert the passing iiuid into gas rapidly. The fluid enters the burner from the pipe B through the hole b, and passes up the port c, across the port d, down the port c, across the port f, to the other side of the burner, up the port g, across the port h, down the port t', and across the port 1i', to the aperture a.

In order to provide for the cleaning of the burner, the screw-plug j is inserted in the port i', which, when removed, permits ofthe insertion of a needle or wire.

All the ports of the burner are constructed out of the solid metal, by drilling in the re quired direction from the outside, and afterward plugging the holes in the exterior.

Operation.

cock is then opened, and owing to the length.

of surface over which the fluid has to pass, and the peculiar impeding character of the ports, while it is at the same time submit-tred to the heat of the body of the burner, the fluid is rapidly converted into gas before it is permitted to escape.

O' lctim The gas-generating burner A, herein described, constructed with circulating-ports b c d cfg he' i andinwardly-iiaring sides a' a for the frameaperture, substantially as and for the purpose set forth.

In 4testimony of which invention I hereunto set my hand.
